Enemies have taken over the Carrington Institute.
You'll have to get the Institute's defenses back online and save some hostages
to finish this mission. Time is a factor, so get going.

From your starting point, turn around and take
the ramp down to the lower level. There are three auto guns in the corridors
down here. At the bottom of the stairs, head through the landing pad area.
In the next hallway is the first autogun. Find the gun control panel just
around the corner and switch it on by pressing B. The auto-defenses will
smoke your attackers while keeping CI employees safe.

Head through the door ahead, moving straight
through the next door. In this warehouse, find the door in the back left
corner and go through. Straight ahead in the shadows of the next room is
a Shield. Run and grab it, then head left tot he next passage, following
the corridor to the next door. Around the corner to the left is the next
autogun control panel. Activate it, then turn around and head past the door
you just came through. Past a crate is another passage. Head through and
loop to the left. The next autogun is above the door ahead. Go through the
door and trip the control panel to fulfill the objective.

2. Minimize hostage casualties

Climb the stairs in this room and exit through
the opposite door. You're in the hangar. Follow the catwalk around until
you reach a side path on the opposite side of the area. Ascend the ramp and
reappear in the main lobby. Take down the Skedar here with the AR34, then
find the elevator and go upstairs.

From the elevator, head left. Duck into the first
room and take down the guard directly in front of you. You have to move fast.
If you hesitate too long, or miss, the hostages will end up dead. Now, spin
right and smoke the second guard. This is tough to do in real time, so use
the Boost if you are having difficulties here. If a hostage gets killed here,
don't sweat it. You'll just have to save both in the next room.

Now head to the room to the right. There are
two hostages here as well. Shoot the one directly ahead first. Often, you'll
get a little help from the female hostage here. She'll usually punch out
the terrorist near her. If she doesn't, turn and drop him quickly. As long
as you save one of the two hostages in this room, you'll be rewarded a Devastator
here. It usually appears next to the desk in this
room.

Perfect objective: Destroy sensitive information

While still upstairs, head over to the furthest
office to the left (when facing out of the elevator). There is a safe in
the corner here. Either equip the secondary function of the Laser and cut
through the metal to destroy the info, or back up and use the Devastator's
Wall Hugger to blow the safe to kingdom come. Either way, objective
complete.

Return downstairs and head toward the weapon
training room. There will likely be a bunch of enemies in the lobby now.
Use the columns as cover, then peek out and kill them. When the coast is
clear, head into the training room.

Note: there are some virtual hostages
in the room next door. Don't bother with them. They are heavily guarded and
needn't be saved.

In the training range, kill the guard to the
left, then quickly scan right and drop the second terrorist. If you have
saved enough hostages (three total), this objective will be complete.

3. Retrieve experimental weapon

Access the computer terminal in this room to
open the glass surrounding the experimental weapon. All you have to do is
grab the RCP-120 to complete this objective.

4. Deactivate bomb

Upon grabbing the weapon, the firing range will
fill with baddies. Retreat to the small wall behind the computer and take
them on with the AR34, killing each as he comes around the partition. When
they've all dropped, head out into the lobby and sprint for the ramp
downstairs.

Tip: You may want to use the Cloak function
of the RC-P120 to make it easier to get downstairs.

Go to the ramp and head below. If cloaked, do
not bother killing anyone on you way down. Otherwise, run and gun with a
fast and powerful weapon like the AR34. When you reach the outdoor helipad,
kill any enemies here, then equip your Data Uplink. Use it to download a
virus into the Skedar ship parked here. The bomb-heavy cruiser will take
flight, exploding high in the air. Return to the main hangar to finish the
mission.
